🧪Atoms are the smallest and indivisible particles that make up matter.
🔬Chemical reactions provide evidence for the existence of atoms.
🔍Advanced technologies like the scanning tunneling microscope allow us to see atoms.
📐Atoms can be split into smaller particles and their sizes can be calculated.
🌌Atoms are the foundation of the universe and play a crucial role in chemistry.
Can atoms be seen with the naked eye?
—No, atoms are incredibly small and cannot be seen without advanced technologies like microscopes.
How do we know that atoms exist?
—Their existence is supported by chemical reactions, mathematical equations, and direct observation using technology like the scanning tunneling microscope.
What are atoms made of?
—Atoms are made up of even smaller particles called protons, neutrons, and electrons.
Can atoms be divided further?
—Yes, atoms can be split into smaller particles, such as protons, neutrons, and electrons.
Why are atoms important in chemistry?
—Atoms are the foundation of chemistry as they determine the behavior and properties of all matter.
